LICART vs NESACAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Licart is a fibrin sealant containing human fibrinogen and thrombin. When applied, thrombin converts fibrinogen to fibrin, forming a stable clot that mimics the final stage of coagulation. It also contains factor XIII and aprotinin to cross-link fibrin and inhibit fibrinolysis, respectively.
Nesacaine (chloroprocaine) is an ester-type local anesthetic that blocks voltage-gated sodium channels in neuronal membranes, inhibiting the initiation and conduction of nerve impulses.
Adults: 50 mg orally once daily.
Injectable local anesthetic: 1% or 2% solution, maximum dose 7 mg/kg (not to exceed 500 mg) with epinephrine, 4.5 mg/kg (not to exceed 300 mg) without epinephrine. Administer by infiltration or nerve block; may repeat at 30-minute intervals.

Terminal elimination half-life of 6-8 hours in adults with normal renal function. Prolonged in renal impairment (up to 20-24 hours in ESRD), requiring dose adjustment in CrCl <30 mL/min.
Terminal half-life: 40-60 minutes (rapidly metabolized by plasma pseudocholinesterase); clinical context: prolonged with hepatic dysfunction or atypical pseudocholinesterase
Primarily renal excretion (80-85% as unchanged drug), with 10-15% biliary/fecal elimination. Less than 5% metabolized to inactive glucuronide conjugate.
Renal: 90-95% as unchanged drug and metabolites (predominantly 4-hydroxypropycaine); biliary/fecal: <5%
